Take a look at the attachment below. As you can see, the figure demonstrates a 90 degree angle such that the surfaces are perpendicular, and hence are independent of the angle of incidence. You could say that this forms a part of a parallelogram -
1500m = 1 sec
9000m/1500 = 6
So, it would take 6 sec to go 9000m
Answer:
It will take 9 hours
Explanation:
If a car travels 100 km per hour and 900 km is divided by 100 it will take 9 hours to travel.
Answer:

Explanation:
The electrostatic force between two electrons is given by:

where
is the Coulomb's constant
is the electron charge
r is the distance between the two electrons
In this problem, we know F=4.0 N, so we can re-arrange the equation to calculate r:
